Steam Family Sharing allows close friends and family members to play one another's games while earning their own Steam achievements and saving their own game progress to the Steam cloud. It's all enabled by authorizing a shared computer.

Sounds neat, but it does look convoluted and complex. I have a simpler system, which is quite revolutionary. It's called physical copies and I can just give them to friends. It's magic.

but you could say that that makes me just as "guilty" as ptman and his family sharing of GOG games.

Sure but...put your hand up if you never copied or borrowed a friends CD, LP (ooh, good old days), DVD, VHS, book or whatever. Seriously, sharing with your immediate friends and family is something that everyone has done forever. It's called being a normal person. As long as you don't share with the world...who the fuck cares? Only some kind of insane, soulless version of Duck McScrooge could care.
